Product Description
PiLZ S4 751104 750104 Safety Relays

The Pilz PNOZ s4 (750104) and PNOZ s4 C (751104) are standalone safety relays designed for monitoring E-STOP pushbuttons, safety gates, and light barriers. The primary difference between the two is their terminal type: the 750104 uses screw terminals, while the 751104 features plug-in spring-loaded terminals for faster, tool-free wiring.

Key Features & Functions
  • Operating Modes: Configurable via a rotary switch on the front panel, supporting manual start, automatic start, and monitored start with a startup test.
  • Input Monitoring: Supports 1-channel or 2-channel wiring with optional detection of shorts across contacts.
  • Outputs:
    • 3 N/O: Safety contacts (instantaneous) for safe power interruption
    • 1 N/C: Auxiliary contact typically used for signaling status to a PLC
    • 1 SC: Semiconductor output for additional diagnostics
  • Safety Standards: Meets high safety requirements (up to PLe/Category 4), featuring redundant built-in self-monitoring and automatic contact testing in each cycle.
Technical Specifications
Parameter Description
Supply Voltage 24 V DC
Current Rating 6 Amps
Unit Width 22.5 mm (compact design for DIN rail)
Response Time Typically very fast (approx. 12 ms) to minimize hazard distance
LED Indicators Power, Input status (In1, In2), Output status (Out), Start, and Fault
Installation & Maintenance
  • Mounting: Should be installed on a 35 mm DIN rail within a control cabinet rated at least IP54.
  • Expansion: A connector on the side allows for the addition of one PNOZsigma contact expansion module to increase the number of safety contacts.
  • Diagnostics: The "Fault" LED and input LEDs help identify issues like short circuits, open circuits, or internal relay failure.
